Emergency Flood Evacuation Route Options for Richmond and Londonderry

Recent flood studies carried out for the Hawkesbury Nepean River System have indicated that communities residing downstream of Warragamba Dam on the Hawkesbury Nepean River floodplain are at a high risk of being flooded during large floods. The Warragamba Dam Flood Protection Program adopted by the NSW Government in February 1993 includes the preparation of a Hawkesbury Nepean Floodplain Management Study. The SES has also developed a Flood Emergency Plan for the region. In the event of a major flood the SES Emergency Plan includes the evacuation of some 10,000 residents of Richmond and Londonderry to safe evacuation centres above the flooded areas.

Two basic route options (A and B)have been put forward for the emergency flood evacuation of Richmond and Londonderry. The following report summarises recent studies undertaken for the preliminary assessment of the two evacuation route options A and B. Aspects such as the risk to safe evacuation from flooding due to the local catchments along each route have been examined. The preferred route option has been assessed together with the order of costs of required upgrading works and the appropriate upgrading standard to be adopted.
